I wonder is that possible for OS to make bad sectors on Hard Drive?
I have bought new HDD on 1Tb WB Caviar Black. I have installed new OS on ext4 partition Ubuntu 12.04.1 LTS. After few days S.M.A.R.T. of the Ubuntu's Disk Utility show that my hard has bad sectors! I have checked on S.M.A.R.T. immediately after installing OS - all was OK. During new OS working I have noticed some strange with HDD - all OS was freezed from 20 sec to 1 min and I have heard like HDD's engine restarting. At the dmes I have found something like this:
[40085.407947] ata1.00: device reported invalid CHS sector 0
My experience with bad hard drives goes back into the late 1990's. You would do best to get the bootable version of Data Lifeguard Diagnostic, available here:
You will find the basic info on how to create the needed CD. Boot from it and check your disk with the 'Quick Test' and if it passes that, run the 'Extended Test'. If it fails either test, you should start the RMA process with WDC.com here:
I suspect your drive is toast as the error message indicates the literal boot sector has failed.
I have an external HDD that is starting to fail, it has some bad sectors. It's a 1TB fujitsu siemens case with a western digital HDD inside.
Eventually I will backup the whole drive with some backup/imaging software. But atm i dont have the free space to do that. Atm I want to copy some video files, but i'm not able to because the drive hangs while copying a certain file, and disconnects. If i try to resume (using tera copy, great tool btw) it hangs again and disconnects...
I don't seem to easily find a tool to copy that one file (and maybe others later), preferably freeware of course.
i have run chkdsk /r on that drive, and about 4 hours in it was at 1% (phase 1,2 and 3 where don't in a few minutes, phase 4 took hours to get from 0). Atm I don't have access to a pc that can run long enough to get the job done in one sitting.
Is there a better tool out there so I could cut this job in pieces? (or faster, but that seems unlikely)
Roadkil's Unstoppable Copier recovers files from disks with physical damage. Allows you to copy files from disks with problems such as bad sectors, scratches or that just give errors when reading data. The program will attempt to recover every readable piece of a file and put the pieces together. Using this method most types of files can be made useable even if some parts of the file were not recoverable in the end.
Unstoppable Copier is freeware.
if that doesn't help, try fixing the drive with HDD Regenerator and salvage your files.
HDD Regenerator is shareware ($39.95, money-back guarantee), try before you buy.
p.s.: i have pretty good experiences with this program, but of course sucsess depends on the severity of the damage
You can try FileSaver. It will copy file in blocks. Even in case that some data cannot be read (after multiple retries) it will continue copy operation (with that data omitted of-course).
I wrote a simple PowerShell script here which allows better fine-tuning than Roadkil's Unstoppable Copier. Precision is up to the cluster size.
Currently I am trying to access the RAW disk/file with it, so that I am less limited and have more recovery options.
